How do blind people know that they've sufficiently wiped?

Funny answer: their dog won't let them leave the room if they smell too much.

Slightly serious answer: bidets are magic.

If there were bidets everywhere, I'd be willing to leave my cave more often.
- Using a public bidet sounds like an awful idea.
- Go live in Japan. Literally bidets everywhere even in public places. My butt had never been so consistently clean.

Taste the paper

That's like evil Skittles

How can you not tell by feel?

There's an app where you can have a seeing person help you. I think its meant for shopping and navigating places but I don't see why they couldn't be used as paper checkers

Are you thinking of Zoom/Teams?

This whole thread is nothing but jokes. The real answer is they wipe their butthole with their finger and then press their fingers together to feel if it's at all sticky.

Get yourself a travel bidet <$20 on Amazon, and start with that. You use warm tap water from your commode.

No installation, but a bit of practice.

My proctologist ranted about general bad wiping habits in the US that damage the hemorrhoid tissue over time. Don't spend your life in sin and misery as I have in the House of the Rising Sun, and stick to only dabbing with bathroom tissue, and use bidets to do the heavy cleaning.

Preach.

How often do you visually check your butthole when wiping?

We are all blind in the bathroom, my friend.

Every. Single. Time.
??? Wtf people, check yo ass, jesus
Fuckin christ, dude. Get some hygiene.
You check the paper, not your butthole
- Please speak for yourself.

I personally don't ever have to look and I'm glad I don't have to

You sound more confident than you maybe should :P

Lot of jokes here, my brother repeatedly has told me he is disgusted by the fact that we look at toilet paper to tell if we are clean. Granted he would have to get the TP very close to his face to be able to see anything. He says he just wipes until he is clean. Not an exciting answer, but that's what I got.
